My Moto X Pure Edition phone randomly died whenever the battery level was below 30%.

TL:DR version: Successful battery replacement went smoothly, but thoroughly removing the old adhesive took forever, and I did not successfully attach the new Precut Adhesive Sheet to the back cover.

Replacement part and kit: iFixit Moto X Pure Edition Replacement Battery Part and Kit (Item code: IF391-002-2) for $39.99.

- My rating: 5 out of 5 stars

- Excellent quality and value

- New battery is an OEM-equivalent produced by LG

- Kit provided everything needed to complete the repair for only $7 more than the part alone

- Minor issue: The guide mentions using 90% isopropyl alcohol for prepping the back cover surface for new adhesive, but the wipe in the kit is only 70% isopropyl alcohol

Guide: Motorola Moto X Pure Edition Battery Replacement

- My rating: 3.5 out of 5 stars

- Fairly comprehensive with some issues

- Photos were extremely clear and helpful

- Major Issue: No detailed guidance provided for applying the new precut adhesive sheet to the back cover. As you can see from my photo, the sheet ended up as a sticky ball, and there is no adhesive holding the back cover on the phone. This should be added as a video guide.

- Minor Issue: Thoroughly removing the old adhesive took forever. Most of the photos showed adhesive still present, so I wasn't sure if it was OK to leave some. Using tweezers and spudger didn't work well. The best tool was the ball of old adhesive (see photo). I kind of wish I had followed the last piece of advice and left most of the old adhesive in place since the new sheet was destroyed in the process.

Step 11, Removing old adhesive: Very time consuming and problematic if you don't successfully install the new precut adhesive sheet. If you choose to remove all the old adhesive, the best tool is a ball of the old adhesive (see photo) used in a press and roll off motion.

Step 13, Disconnecting the battery connector: The tiny bit of plastic on the end broke off, so the spudger could any leverage. I had to carefully use the tips of the tweezers to do this.
